Calibrate B+ threshold.
If required, you can use the
Calibrate B+ Thresholds
page ( Figure 2.20
or Figure 2.21 ) to adjust the thresholds used to disconnect and reconnect the B+ dc voltage to the
XR6/XR3 transmitter.
To calibrate the B+ thresholds, perform the following steps (see Figure 2.20 or Figure 2.21 ):
1. Use the
Up
and
Down
buttons to select the appropriate
Discon.
(disconnect) level, noting it
is in the left-hand

Edit
button, then press the
Up

Save
button to save
your calibration. (Pressing the
Cancel
button discards your changes.)
CAUTION:
Do not calibrate B+ thresholds unless specifically instructed by Nautel personnel.
Decreasing the Recon. (reconnect) level can damage the transmitter.
